Letters Patent No. 90,712, dated June 1, 1869.

strove-S ELF.

The Schedule'refened to in these Letters Patent and making part of the same.

To all whom it may concern;

Be it known that I, DANIEL D. WHITNEY, of Leomiuster, Worcester county, in the State of Massachusetts, have invented an Improved Stove-Shelf; and I hereby declare the following to be a full and exact description thereof, reference being had to the accom-.

panying drawings, forming part of this specification The nature and essence of my invention consist in .a vertical standard for an adjustable shelf, having a series of horizontal grooves in its surface, by means of whiehgrooves shoulders are formed, against whichtached to a flat-foot, block, or clamp, and set upon or be fastened to the body, with which it is connected at different points in its height. Horizontal grooves B B extend around it.

The adjustable shelf 0 has, at one end, and-at right angles to its broad. surface,a,hole, which'fits upon the standard and-holds it in a horizontal position upon the vertical standard.

To prevent the shelf slipping down upon the standard, the catch D is used, and may be constructed in the form shown, or in any otherform, and may be attached to the shelf, or otherwise applied, as may be thought best.

The catch is so arranged thatthe spring presses it constantly against the standard, s'ufiiciently hard to prevent its slipping over the shoulder on the standard formed by said grooves, or other means, and thus holding the shelf in position while it is allowed to revolve horizontally around the standard.

As this catch is pressed constantly against the standard,with sufiicient force, by the action of .the spring, there is no danger of the shelf slipping down, on being jostled or jarred, a result that might cause great annoyance,.as well as loss and damage.

.When it is desired to raise or lower the shelf upon the standard, the spring-catch is thrown out from the standard, so as to clear the shoulder, and the shelf may then be raised or lowered at pleasure, until the catch is in position to be received upon another shoulder, when it is immediately forced to the desired place by the action of the spring, and the shelf becomes confined without further care or attention.

The foregoing being a description of my improvement in an adjustable shelf-standard, and spring-catch to confine an adjustable shelf upon its standard,

What I claim, and desire to secure by Letters Pat ent, is-- 1. The combination, with a stove-shelf, (l, of the spring-catch D, for holding the same-at the desired height, by contact with a projection or shoulder upon.

the supporting-standard, substantially as described.

2. The combination of the shelf 0, provided with a spring-catch, D, with the" vertical standard A,'having horizontal grooves or recesses B, substantially and M. W. STRATTON, S. '1. RUMERY.
